ADJUSTABLE MARKING GUIDE.

Application filed Au ust'ai, 1926. Serial No. 130,729.

My invention relates to adjustable marking guides, and the object of myimprovement is to supply an adjustable device of this class which hasmeans for indicating on opposite faces'of a block places for markingconstruction lines at the same relative Preparatory to the marking ofconstruc tion lines upon opposite faces of a block of stone, such as atombstone, and in which the design of the sculpturing includes lines tobe engraven at the same level or height on said faces, it is desirableto provide a device for indicating the exact position of such a line onone face relative to a primary line to be drawn upon the other face, toinsure exactitude in the work and to save time and labor cost.

My improved device is intended for this purpose, and has been foundeffective in practise.

My said device is composed of a pair of guide-bars or parallelstraight-edges 1 and 2, whose upper edges are smooth and in the samehorizontal level. The guide-bar 1 is the wider vertically and has at itsfour corners horizontal transverse holes to receive therethrough theterminations, threaded, of the vertically spaced parallel members a and5 respectively of a pair of like looped rods. These rods are bent twiceat equal distances from their middles providing a vertical con nectingpart 6 with the members t and 5 parallel. The narrower bar 2 has neareach end short slots 7 which are transversely alined with the upperholes in the guide-bar 1. The upper members at of the loopedrodsaforesaid are first passed loosely through these slots 7, the lowermembers 5 passing below the bar 2. The terminations of said members arethen passed through the holes in the bar 1 after nuts 14 and 13 havebeen mounted on their threaded tern'iinations,

and then wing-nuts 8 and 9 above and below are mounted on theterminations to clamp the bar '1 between them and the nuts 14. and 13. ij

The device is then complete for service as above described, but I haveshown in combination therewith means for supporting the device forvertical adjustment relative to. a block between thebars 1 and 2 asindicated by dotted lines in Fig. 1.

This means comprises a third bar 3 which is of the same length andplaced below the bar 1 in vertical registration therewith. Bars 10 areused as pivoted connectors between the ends of the bars 1 and 3,- theupper ends of the bars 10 being pivoted on the terminations of the lowerloop members 5, and the lower ends of the bars 10 being pivoted on thethreaded terminations of bolts 12 whose stems are passed through holesin the ends of the bar 3 and secured by wing-nuts 11.

In practise, as shown in Fig. 1, the device is mounted about a block andthe connectors 10 swung tolift the guide-bar 1 to the desired heightalong one face of the block, the wing-nuts then being tightened tosupport the bar 1 rigidly upon the bar 3 and the latter upon thesupporting surface beneath. A line may then be drawn across the face ofthe block guided by the upper straightedge of the bar 1. The bar 2having been moved along the loop members 4 and 5 to contact with theopposite face of the block, the upperedge of the bar 2 will be at thesame level as the upper edge of the bar 1, so that a line may be drawnon the block along the .upper edge of the bar 2 at said level. In caseof any slight difference in' thickness in the block between the bars 1and 2, the

.slots 7 permit some relative movement to the bar 2 to swing slightly tothus contact evenly with the abutting face of the block. The lower bar 3and its connectors 10 may be dispensed with if desired for somepurposes, by separating the bars 10 from the lower terminations of theloop rods.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is: 1

1. A device of the character described, comprising a pair of opposedbars with like edges in the same plane, looped rods with parallelmembers in different planes, spaced apart and terminally secured to theend parts of one bar, the other bar being loosely slidably mounted uponsaid rods to be adjustably moved to and from the first-mentioned bar.

2. A device of the character described, comprising a pair of opposedbars With like longitudinal edges in the same plane, projections on theend parts of one bar, the other bar being slidably mounted upon saidproject-ions to move to and from the first-mentioned bar, a basalsupporting member, adjustable connections between said basal member andthe first-mentioned bar, and means for releasably securing saidconnections to said basal member and said bar to hold the bar in adesired position of adjustment relative to the basal member.

3. A device of the character described, comprising a pair of opposedbars with like edges in the same plane, looped rods with parallelmembers in different planes, spaced CARL H. MOLINE.
